T all whom it may concern.'

Be it known that I, VILLIAM H. TUonr, a citizen of the. lnited States,and a resident of Eagle, in the county of Vaukesha and State oflVisconsin, have invented certain new and useiul Improvements in Concrete-Molds; and I do hereby declare that the following is a full,clear, and exact dcwall in process scription thereof, reference heilighad to the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

This invention relates to improvements in concrete molds and moreparticularly to devices of the character described adapted for` use inconnection with the @instruction of retaining walls and foundzftions ofbuild-- ings and similar structures involving a sulicient degree ofuniformity and regularity in outline as to permit in its constructionthe repeate'rl use of a` manually operable device.

The object or" my invention is to provide a coi'icrete niold that issimple in construction and operation and embodying such features willrender it exceedingly flexible` :nid emirvenient in its application tothe art` ,of linildirg no and cost involved in build` of that character.

'1 to 7, inclusive, a form of my device is shownaswould be used in the construction of a Wall of uni form thickness, andherein illustrated as consistingr of two sections at right angles toeach other, joined at their ends to form a corner. (See Figs. 4, 5 andG.)

The mold embodying my invention com prises, in general, frame members11, 11. and mold boards 12 and 13, supported by said frame members. Theframe members are spaced a suitable distance apart and arranged inparallel relation to each other and in transverse relation to the saidmold boards. The mold boards 12, 13 are secured to the frame members 11,11 in such a man ner that one of said boards, 12, is in fixed relationto the 'frame members, so as to maintain a vertical position, and theother of said boards, 13, is adjustably or movably attached to the framemembers so as to be normally maintained in a position parallel with theboard 1i), while it is capable of beL ing moved in a direction towardand from said board 12 and out of parallel relation therewith, for thepurpose of applying the mold to the wall in position to receive theconcrete and to release thc mold in the man-- ner hereinafter to bedescribed.

Referring now more in detail to the con` struction of the frame members,cach oi' the same comprises a rigid frame 14, 14, consisting of twopairs of horizontal bars l5, 1G, located one :bovethe other and Vjoinedtogether at their ends by means of connecting members 1T, 1T. shown` asmade of curved form. The said pairs of longitudi4 nal bars are alsospaced apart laterally. forming a longitudinal space between them, saidspace bring maintained by inserting the ends of the connecting membersbetween thc ends of the longitudinal bars, and securing all of themembers together by means ol' rivets 18.

Each of the rigid frames 14, 14 supports two vertical arms 18- and 20,one of the arms, 19, being in rigid connection with the frame, and theother having movable or swinging connection therewith. Said arm 19 ismounted within the space between the hori zontal bar members and issecured thereto by means of bolts 21 extending through the upperhorizontal bar, members and the upper extremity of the vertical arm, andthrough the lower bar members 16 and the als Y the lever a s saidvertical arm. The lower portion of said vertical arm '19 projectsdownwardly below the frame 14 and to the same is fastened the mold board12. The fastening means shown consists of angle members 22 attached byrivets or otherwise to the outer surface of said board. The othervertical arm 20, which is movable, as stated, is mounted within thespace between the long'itudinal bar members l5 and 16, at a distancefrom the arm 19. The arm 20 is pivotall connected to the lowerhorizontal bar mem rs 16 by means of a pivot bolt 23, the upperextremity of the arm projecting upwardly between the upper bar members15 and disconnecting therefrom so as to render the arm free to beoscillated about its pivot bolt 23. As in the case of the vertical arm19, the arm 20 likewise extends downwardly from the frame 14 and isaiiixed to the mold board 13 by means of similarly arranged anglemembers 22. Referring now to the mechanism illustrated for operating thesaid movable arm 20, the same comprises the following elements: A handlever 24 (Fig. 3) is pivotally mounted between the upper horizontal bars15, 15, with its pivotal axis immediately adjacent to the path ofmovement of the upperV extremity .of the vertical arm 20. Said lever ispivotally supported b means of` a ivot bolt 25 extending throng ortdistance from its lower extremity. The pivot. bolt is located on thebars 15, l5 at a short distance horizontally from the arm 20. The lowerextremity of the lever is slightly rounded and adapted to have slidingcontact with the adjacent edge of the vertical arm 20, when the lever isswung downwardly from its vertical position, as shown in full lines inFig. 3. The arm 20 is provided with a link member 26 (Figs. 3 and 3),secured thereto at a point immediately below the horizontal bar members15, said link extending parallel with said bar members in the dlrectionof the lever 24. The link member is preferably of U-shape, as seen inplan View, and its ends embrace the arm and are secured thereto, bymeans of a bolt 27. Said link member is adapted to engage, at its outerend, the lower extremity of the lever 24, when the latter is Mswung ormoved toward its vertical position (as shown in dotted lines in Fig. 3),and from its position in contact with the upper extremity of the arm,and by this engagement to transmit a movement to the arm 20 about thepivot bolt 23. The upper end of the lever 20 adjacent to the pivot ofthe operating lever and the end portion of the link member for-m, bearinsurfaces, facing toward each other, on w ich the lower end portion orarm ofthe operating lever acts, in one instance to throw the lower endof the arm 20 .inwardly and'lockthei same from movement, and, in theother instance,

to swing the lower end of said arm outwardly. By swinging the lei'er 24toward its upright position the upper extremity of the arm 2O is drawninwardly toward the lower extremity of the said arm 20 is swungoutwardly from the said arm 19, and as a result the space between themold boards 12, 13 is increased. By swinging the lever 24 lowerextremity or arm thereof is disen gaged from the link and coacts withthe sur` face of the arm. This engagement between the arm and lever, inthe nature of a cani action, effects a movement of the arm 20 in theopposite direction and to a position in which said arm 20 is parallelwith the armv 19. The upper extremity of the lever 24 is preferably bentoutwardly at right angles to the horizontal bars 15, to form an angularportion 28, the same acting as a stop to limit the downward movement ofthe lever, as well asa convenient handle for grasping the lever. Whensaid lever is in its maximum contact with the horizontal bars 15, thelever also acts to lock the movable arm 20 in its vertical positionuntil. released bygrasping the lever and moving the same upwardly.

Referrin more particularly to the construction o? the mold boards, thesame may be of any desired length and width, depending upon the natureofthe work Aor the size suggests,would ordinarily be of woor-i thoughother materials such as sheet i? weight would not make its useundesirable.

A device embodying the features of con ited in its use to theconstruction of a mm tinuous straight wall of a prixletcrininm!thickness having parallel and vertical faces and devoid of angles,corners, openings, or spaces -therein. such a wall would referably beaccom plished in stages by t e repeated use of tlm mold in the followingmanner: The lirst stage is'ordinarily constructed by placing otherSuitable foundation with the mold, boards in parallelposition, andfilling the space between the mold boards with een crete in plasticcondition. After taniping the concrete down, with its to ,surface evenwith the upper margins of the boards` the mold is released from thelower part of the wall thereby formed, by actuating the lever 24 in themanner stated. Theoperation is repeated, by moving the mold endwise to:i position in which one extremity of the mold overla s the end of thewall section just formed), until .the first stage is conn-plated. "Thesecond sta e is similarl formed. upon the first stage,rt e moldh'in t isinstance be arm 19 (Fig. l), and in like manner the` downwardly from itsvertical position, the

downward position with the bent portion in may 'be employed where thein( eased y struction thus far described, would ne liinY the mold uponthe surface of the ground or im.

of the mold. .The mold boards, as the naine The operation of building tf .las

ing supported upon the previously com` pleted part of the wall, byplacing the mold, with the movable board in its released position, insuch position that the lower margins of the mold boards overlap orembrace the ulpper portion of the completed portion of tie wall, asshown in Figs. 1 and 2, and then swinging the lever 24 to its horizontalposition, so that the mold board 20 operated thereby will be drawninwardlytoward the stationary mold board, and a clamping engagement ofthe mold with the completed part of the wall will be effected. In thismanner the several stages are added one upon the other until the entirewall is com-.

pleted.

To make the device capable of use in the construction of various formsand thick# nesses of walls, I have provided certain features in thestructure of the mold,iwhich` constitute a part of my invention.Referring to these features in detail, I provide, for the vpurpose ofconstructing walls of different thicknesses, a plurality of apertures 29in the upper and lower horizontal bar members 15 and 16 of the framemembers 11, (Fig. 1). y

These apertures are arranged in pairs, each pair being in verticalalinement and adapted to receive the bolts 21, 21, which secure thestationary arm 19 and mold board 12 rigidly to the frame members. Bymoving the said arms to one or another pair of aper the same in verticalpositures and securin the said bolts, the space tion by means o betweenthe mold boards may thus be varied` 'to permit the construction of wallsof differ-g cnt thicknesses. t

. To render the mold suitable for construct-v ing the corners ofbuildings or walls meeting:

at an angle, I provide a construction in the :mold yboards as follows:At one end of at least one of the mold boards 12 the same is out away-atits lower edge to form .a rectanguiar rabbe't 30 (Figs. 1 and 5), suchrabbet extending inwardly from the end of the board and upwardly fromthe lower margin thereof, so as to forni an endportioii in the board ofreduced width. The length of the rabbet is slightly greater than thethickness of the wall under construction, or the distance between theinner faces of the mold boards. and the vertical width of the rabbct isequal to the width of the lower marginal portion of the mold boardswhich ordinarily lembraces or overlaps the upper portion of thecompleted wall section, when the mold is clamped in position upon suchcompleted section. In the downwardly facing surface of the mold board,at the rabbeted or cut away portion, I also provide a plurality ofnotches 3l., preferably equidistantly 'spaced (Fig. 5) the purpose ofwhich is hereinafter described. For use in constructing .any one corner,such a rabbet will need to be provided only in the board which is.applied to fand 5, the gate is now put in place. the

form the inner surface of the wall, but both boards will commonly beprovided with such a rabbet, so that'the same mold may be used forformin reversely arranged corners, or those in w ich the transversewall, at the corner toward which the mold is moved' as the workprogresses, extends either to the right or left from the wall sectionfirst completed in the formation of the corner.

At the end of the /mold boards adjacent to the recess 30, I provide anend board or gate 32, the same comprising a rectangular niember, whichmay be made of wood, provided, upon its outer Aface and along its sidemargins, with laterally extending metal flanged members 33,securedthereto. These flanged members overlap the ends of the moldboards and are retained within spaces at the ends of the mold boards,formed by means of angle members 35, 35 secured to'the vertical endmargins of the outer surface of the mold boards and provided withinwardly extending flanges or parts which are spaced outwardly from theends of the mold boards. The flanged members 33 are provided at their'upper ends with transversely bent portions 34, adapted to project overand engage the upper margins of the nio-ld boards and to thereby affordadditional means 'for retaining thc gate securely in place and limitingthe downward movement thereof. By this arrangement the gate may beeasily removed or applied when desired, and acts to provide an end facefor the section of the concrete Wall being formed.

The construction of the recess 31 and thrgate 32 is particularly usefulin the cor` struction of corners, as before stated.

Now, referring to the operation of con structing a corner, Figs. l and,5 show tbc iff-f itu" which intersects the section 10 of the nudi ai.`

right angles thereto. liv reason of the tart that the upper surface ofthe said compiutiportion 36 of the wall lios in tinA plano oi ibo uppersurface of the comple-ed portion in,

it would obviously be inuiossible to place the mold in the positionsuggested, were it not. for the presence of the rabliet 30 which por--mits the end of the innern'uist board r2() ts; extend over thewall-section 36, with the upper portion of the said section 36 comming:L

the said recess. Having clamped the inon the wall 10 in the positionshown in ner surface thereof being in vertical ein@ ment with the endface of the wali www; L

10. The wall section formed by means of'f the mold in this positionextends to the end of the Wall section 10, and is quite independsent ofthe section 36. Having completed this portion, the mold is removed andclamped to the section 36, in a position at right angles to its priorposition, as shown in Fi 6. In, this instance, however, the end of t emold, not provided with the gate and recessl is` laced adjacent totlie'section just completedpy in order that the end of the innermost ofthel two boards 2G may abut against said section, and a smooth jointbetween the 'sections formin the cornerfmay be thereby obtained.'Furthermore, it is often desirable to in-v sert. between the horizontalsections of the Wall, a series of reinforcing wires 37, which arelaid,upon the surface of the completed.- portion and bent at the cornerto extendl along tbe section 36. The purpose obthel notches 32 is,therefore, to permit the said wires to extend at right angles to themold@ board l2, without interfering with the proper placement of themold upon the Wall f section 10 and the engagement of the section 36with the recess 30. The use of the recess 3i and the gate 32, in.connection with l the mold boards made and operating as described,eliminates the necessity of constructing a special corner mold such asis commonly used for forming the intersections of two wall sectionsmeeting at right angles. In ad i itiou to itsusein connection with thev.tion of corners, 'the gate 32 is particui. ity useful where, in theconstruction of a wail. space or open area is desired to be forni/ed, asfor instance where windows or doors are to be placed in the walls of abuilding. In this capacity the gate serves to form the vertical tace ofthc space into which the window or door sash is fitted, in that itprovides a vertical end face f or each section at either side of thearca or opening.Y It is to he iinflcisimul in this coinicction thateither i or both ends of the mold boards may be arranged to receive agate 3i?, and so, also, a rabbct may be formed in any one or all of theends of mold boards, aithough for urof this invention I have illustratedbut a single gate and rabbet. The presencev of the additional gate andrecess would obviously increase the adaptability and usefulncsa of heincid to the uses for which it 1s designed.

In liig. 7 of the drawings isshown a modified construction of a moldmore particularly adapted for constructing walls, one face of which istapered and the other face vertical. YSuch a construction is often em`ploycd in the building of retaining walls, where the resistance oflateral pressure requires a greater thickness of material at the naseci? the wail than at the top. This form of incid differs from thathereinbefore de scribed only in the arrangement of the frame members 38(one of which is shown in Fig. 7.) In this instance, both of the arms39, 40

are in pivotal engagement with -the lower horizontal frame member 41,the arm 40 being mounted and operated in identically the same manner asbefore described. 'l` he upper extremity of the arm 39; however, is notsecured to the upper horizontal bar members 42, but is free to oscillatetherebetween. Adjacent to the extremity of the arm 39 is attached oneend of a turnbuckle 43, the oppositeend thereof being secured to theadjacent vertical connecting bar 44. By adjusting the turnbuckle 43, thearm and the mold board attached thereto may be moved about its pivotingpoint to any desired angle, as shown in1 dotted lines. In this manner a.wall having a tapered face of any desired have their upper and lowermargins inclined 57 at an angle to afford the proper degree of taper tothe posts to be constructed.- The boards are provided with angle members46, by means ofwhich the boards may be se cured to the frame members ofthe mold, in the same manner as the boards hereinbefore described. As apreferably construction, I also provide gates 47 and 48, at the endsI ofthe boards, for the purpose of providing proper end support for thepost. The con- 5 struction and manner of mounting the gates being thesame as before set forth, a detailed description 'is thought to beunnccessary. To construct afence post the mold would be )laced upon alat surface with the gates properly inserted in the ends of the moldboards, the space would be filled with concrete and the upper surface ofthe concrete properly leveled to coincide wit the upper marginsof theboards. When the concrete has become suiiiciently hard the mold isVreleased in the usual manner from the completed post.

It is to be understood that the details of construction of a concretemold embodying my invention may be variously modified withoutdepartingfrom the spirit of the invention and for that reason I do not' wish tobe limited to the construction herein described and illustrated, exceptin so far as specifically pointed out in the appended claims.
